To all whom it may concern:

Be it known that I, MAn uus H. Locuwooo, residing in the borough of Manhattan, city, county, and State of New York, have invented certain, new and useful Improvements in Type-Writer Tabulating Mechanism, of which the following is a specification. 7 i

My invention relates to the adj ustment of the stops carried upon the typewriter oarrings and more particularly to mechanism whereby the operator is enabled to set the stops to the desired columnar position from the-front of the t pewriter and without the necessity of han bug or sliding the stops with the fingers; the stops being readily located or ad]llSl.0d.Wltl'l reference to and by the aid of the regnlarscale and pointer at the front of the typewriter.

The invention may be applied to various styles of typewriters and used in connection with various styles of tabulating mechanism,

but for convenience I have shown it in connection with a denominational tabulator' on the well known Underwood typewriter. The general plan of this typewriter will be found in Patent N9. 633,672 to H. L. and F. X. Wagner, September-'26, 1899; while a tabulator of the denominational type will be found in Patent 956,144, to J. C. McLaughlin, April 26th, 1910.

The details of the invention may be varied in many ways within the knowledge of the I have illustrated in the accompanyi'n drawings several ways for mounting an manipu sting the stops in carrying out my Figure 1 is a plan view illustrating one form of the invention, together with parts of the typewriter and tabu'lator. Fig. 2 is a perspectiveview out one form of the invention; F 3 is an enlarged sectional view taken at --3 of Fig. 1. Fig. 4 is a front elevaion of one-form of the stop posi ioning means. Fi 5 is sectional view at i5-5 of Fig. 1, and shows'a detent for holding the stops in either position. Fig.1 fifillustrates another method of mounting, rotating and securing the stops. Fig; 7 1s a sectional view ta and securihg the stops, and-Fig. e9 showsone of the stops afl withthe hubinsection;

g n at 7-7 ot F g- Fig. 8 isa sectional viewlof another 'n'iethod of rotating Reference being had to Figs. 1 to 5 inclusive, 1 represents the frame of a typewriter and 2 the carriage reciprocating thereon; 3 beingthe carriage tract rod secured to the rear of the frame 1. The scale 4 is secured to the front of the typewriter frame and a pointer 5, secured to the carria e, cooperates therewith in the usual and wel -known manner. The typewriter parts shown represe conventional y parts of the well known Underwood typewriter and only sufiicient parts are shown to illustrate the methods of applying my invention.-

The denominational tabulator, being well known, is only represented by the box 6 in which the plungers 7 are adapted to slide vertically. The top of the box is capped b the o n rectangular plate 8 throng whic .the p ungers 7 are thrust and above which they are caused to project when brought into action by t e'operation' of a tabular key. Instead of th usii'al tabulating stops or tappets adjustably carried upon the carria I jarring of the machine while the stops are disengaged from the securin rack for resettingyor there should be so cient friction to hold the steps that have been set while others are adjusted to the desired positions. Such a friction spring is shown at 31? in Fig. 9. y

From the o eration of the mechanism, which is full described later, it will be a parent that the length of the hubs 14. shou d be some multiple of the letter space distanee, which is usually 1/10 inch-so that when bunched, as illustrated in Fi .1 at the left end of the rod, the stops wi enter the notches of the she securing rack 15. A rack 15 is secured to t e brackets 10 or otherwise adapted to 006 crate with the stops13 and revent them rom sliding on the rod 11.

to be, rotated or moved into or out o "the ave mounted upon the rear oi the carriage.

n my inventionthe. stopsare ada ted secured position in any desired manner, and

will be at 40 in the form shown in Figs. 1 to 5 inclusive the hubs 14 of the stops'13 are provided with splines or keys 14" adapted to fit and slide in the key-way 12 along the rod or shaft 11, so that when the rod is turned all the stops thereon will be rotated either into or out of the rack 15 as desired.

Any suitable or convenient means may be used to simultaneous] movethe stops in either direction. In t e resent instance a handle 16 is secured to t e end of the rod 11 or otherwise arranged for convenience in rotating the stops. Aug desired or suitable means may be employe to retain the stops in either the secured position or in position to slide along the rod. In Fig. 5 one method is shown wherein the collar 17 is secured to the rod ll'near the bracket 10 and is provided with cam or detent notches 18. A friction" roller 19 is mounted in the end of a detent spring 20 and is adapted to rest under ressure in the notches 18, and thereby\ hold t e stops 18 in either of the'positions desi ated. A scale 21 may be secured to the rackets 10 and extend along and over the rod 11 to indicate the letter space osition of the sto s. The graduations o the scale 21 shoul correspond to the graduations' of the scale 4 at the front of the machine so that when .the pointer 5 is at 40 for instance on the front scale the stop 13 as shown by the scale 21 and will be in position to cotiperate with the key actuated tabulating plun r 7 at the ex treme left of the series, and ereby stop the carriage so that in tabulating thefdecimal point will come at the scale position 40 as shown by the front scale 4.

In order to osition or set the stops from the front of t emachine and according to the indications of the front scale 4 and pointer 5 there is secured to the plate 8, or other'relatively fixed part of the' machine a stop :positioning means which ma be 0 an suitable or .,preferred constructionbut is liere shown as a pair of forwardly extending pawls 22 pivotallymounted in the su porting block 23, the pivot pin being 111 1- cated at 24. The forward on s of the pawls are spaced apart, slightly more than the thickness of one of the stops 13, and each is beveled on the under face at 22" as shown in Fig. 4, so that when the stops are in the field or path of the pawls one -of the ate 5 will lift one of the pawls .bystriking tie beveled under face andbe stopped in the s ace between the pawls by stri' ace of the other pawl, when carriage is reciprocated or moved in either dlrection.

Gravity pawls are here Ehown-but it will readily be understood that spring pressed pawls may be substituted therefor as well as pawls or catches of other shape. The

- cated by 'dotte block 23 may be located at any suitable or preferred position with reference to the carria e, but should be in position to locate the in ividual stops 13 according to the scale 4 and in the proper relation to the key actuated plunger or plungers 7 of the tabulator. In connection with the denominational tabulator, as shown, the block 23 is located so that the stop space between the two pawls 22 is substantially in line with the left hand, or decimal point plunger 7; or is so located that when the t ewnter carriage is atrest any stop 13 hel between the pawls 22 will readily pass into one of the notches of the secu'ring rack 15 and thus secure the stop at the scale osition indicated on the front scale4 of t l: point it is desired to have the decimal point come'when' tabulating.

As previously stated various methods of carrying out my invention may be emplo ed and Figs. 6120 v8 inclusive show some at or forms. In thelform shown in Figs. 6 and 7, a, rod 29 upon which the sto s are adapted to slide is mouli ted between t e brackets 10 and secured thereto. The etc 5 30, fitted with hubs 31, are provided wit gear teeth 32 extending over a: part oftheperi h'ery and adapte as shown, to'mesh with the pinion teeth 33 out on the bar 34,which bar extends lengthwise of the carriage between the brackets 1Q and is pi'votally mounted in said brackets. The lower extension of the bar 34 is formed into a rack 35 by the transverse notches 36 cut therein. The rack notches v :16 are adapted to receive and secure the sto s 30 so that the will not slide along the ,rod 29 when tabu ating is-being done, in which there would be a coiiperation or engagement of the stops with the key actuated plu'ngers 7. The stops 80 aswith the stops 13 are adaptedto be'rotated into or but of the secured position as indicated in Fig. 7. In this form the stops are rotated by the movement of the pinion teeth 83 which act on the teeth 32 of'the stops, and thus the stops will be disengaged from the rack and brou ht into the position indilines, to. enga the stop positionm' pawls 22, which are re shown as similar othose previously de'scribedwith reference to Fi 1 to 5. In thiscase (Fl' 6 and 7) the andle 37 is attached to t "piyotal extension of the bar 34 and is ads ted tofturntflie pinion teeth 33 .and swing t e rack 35, and thereby disengage the stops and rack and bring the sto s into the field of the stop position ng paw s 22. It is not however necessary to swing the rack when the stops are turndpand in the form shown in Fig, 8, therackz40, which corresponds to the rack, 15 of the form shown in Fi 3 is fixed, "as the first form described, w ile the pi on rod 41 is adapted to be turned by ahandle37 as in the form shown in Fig.

7. The stops 30, the rod 29 upon which the stops are mounted to slide, the pawls 22 and other details in Fig. 8 correspond to similar parts shownin Fig. 7. In each of the forms shown in Figs. 6 and 7 and in Fig. 8 a detent spring or other means may be employed to retain the stops in either the secured position in the rack or in position to be engaged by the stop positioning catch pawls 22. A friction roller detent similar to that shown in Fig. 5 and adapted for the same purpose is indicated in Fig. 6 at 20 and works in notches in the bar 34 similar to 18 in Fig. 5.

To set or reset the stops, the operation as viewbd from the front of the machine 'is as follows: Before beginning the actual setting operation, the stops 13 (or 30) may be bunched together at one end or the other of the rod 11 (or 29). For example, if the stops are scattered along the rod at different positions-and in engagement with the rack 15 (35, or 40) and it is desired to reset them to other and different columnar positions, the typewriter carriage is first moved to the extreme left and then the stops are released from the rack by manipulating the handle 16 (or 37) which rotates the stops. The detent spring 20 will then hold the stops in the disengaged position and in position to be engaged by the stop positioning catch awls 22. The carriage is then drawn toward the right as far as it will go, when it will be seen that the stop farthest. toward right hand end of the rod will be the first to be engaged by the catch pawls and will be held thereby and caused to slide along the rod, and the hub of this stop will in turn strike and carry along the other stops until they are closely bunched at the left hand end of the rod. It will be seen that the first stop enga ed by the stop positioning catch will still remain in engagement therewith. Now the carriage is released and moved toward the, left in the usual manner, to the point desired for the column, as indicated by the regular scale and pointer of the typewriter, after which the handle 16 is thrown back to normal position, thus disengaging the stop from the stop positioning catch and reiingaging it with the securing rack, ready for 'cotiperation with the tabular plungers. To set additional stops, draw the carriage toward the right and a airr' throw the sto 8 out of the rack and into the field of t 0 stop positioning catch so that the next stop comes into engagement with the catch, then move the carriage toward the left, as before to the scale position desired, and move the handle 16 as before, to release the stop from the catch and secure it in position by the rack, repeating the operation until the desired number of stops are set. The friction between the stop collars and the shaft is made sufficient to prevent displacement of the stops while the various stops are being set in succession as described. The manipulation of the car riage would be reversed if the stops are first bunched at the right hand end of the rod. When all the stops are positioned as desired, they are again secured from sliding by turning the handle to normal position and recngaging the stops and rack, any unused stops remaining bunched at the end of the rod out of the tabulating field.

Various changes may be made and various forms em loyed without departing from the spirit an scope of my invention.
